2 BACKGROUND OF THE INVENTIrJN
3 In those known cases in the prior art, a plurality
4 of elongated pipes have been accumulated in a bundle and then
tightly secured together with a steel wire or band or the like.
6 This binding method has been widely adopted in the fields of
7 transportation due to its relatively simple process. On the
8 other hand, there are some disadvantages in that the elongated
9 pipes are subjected to possible damages destroying protective
coatings by direct contact with the steel wire. Moreover, since
11 the bundle formed of a plurality of elongated pipes is encircled
12 and tightened by the steel wire which contacts only with some
1
CA 02219363 1997-10-24
WO 96/34221 PCT/US96/06009
1 localized or restricted surface portions of each of
2 the outermost disposed elongated pipes, those pipes within the
3 bundle may shift and the bundle is liable to crush or deform
4 during transportation or storage in a stacked condition. Thus the
bundle is unstable and therefore unsafe and difficult to handle.
6 Furthermore, in this conventional method, no countermeasures are
7 provided for protecting each of the elongated pipes against bends
8 or dents.
9
If cans are the articles being packaged, the beads of
11 the cans have a tendency to cause the cans to shift within the
12 package and make an irregular shaped and loose package. Numerous
13 attempts have been made to apply means for maintaining proper
14 alignment through locking devices or separators, and and the like.
Such means have proved either very difficult to apply or costly in
16 application. To overcome shifting and deformation of the package,
17 a resilient preformed spacer can be placed between the units in
18 the package.
19
The means comprises an elongated bar having a
21 plurality of spaced indentations along at least one of the
22 elongated surfaces. The indentations are suitable for receiving
23 the rolls of material. The thickness of the bar adjacent the
24 bottom of the indentations provides sufficient space to protect
the rolls. The width of the bar, with respect to its height,
26
2

WO 96!34221 PCT/US96/06009
1 provides a self-stabilizing property which prevent
2 tipping. The bar is formed of a material of sufficient
3~ flexibility to permit limited relative movement among the
rolls of
4 the stack while at the same time being of sufficient strength
to
prevent crushing of the stack. Expanded polystyrene foam
is
6 suitable for use in 'the supporting and spacing members
of the
7 present invention.
8
9 The elongated bars, rods, or generally tubular members
are placed between the rolls and materials handling apparatus
such
11 as a pallet, between the various layers of the stack, and
on top
12 of the stack.
13
14 According to this prior art the binding device for a
plurality of elongated pipes comprises a pair of pipe reception
16 blocks, first and second sleepers interposing the blocks
17 therebetween, and a bundling strap encircling a pair of
the pipe
18 reception blocks, and the first and second sleepers. A
plurality
19 of elongated pipes are disposed side by side or in transverse
arrangement with respect to the longitudinal axes of the
pipes
21 each within a space defined by the concavities formed on
one
22 surface of the blocks. This assembly is completed and integrated
23 by a tightly encircled bundling strap means along the traverse

1 surface of the assembly. This assembly may be stacked
2 in overlying arrangement with one or more of other similar
3 assemblies. ,
4
The pipe reception block may be made of two regions of
6 different material, one being the region where the concavities are
7 formed and the other being the region where the surface contacting
8 with the sleeper is formed. The former region is preferably made
9 of a veneer plywood. The different materials are fixed together
with an appropriate adhesive agent. The pipe reception block thus
11 constructed has sufficient mechanical strength to bear against
12 deformation so that it protects the elongated pipes form
13 deformation and also enables to decrease the height of the
14 sleepers which might have otherwise been of a considerable volume
so as to withstand the external forces imparted during handling or
16 transportation.
17
18 Another prior art device discloses a roll spacing and
19 supporting structure including an elongated bar of expanded foam
material, such as polystyrene, for use in palletizing rolls of
21 material and protecting such rolls against damage in handling and
22 shipment. Such elongated bar provides a plurality of spaced
23 semi-cylindrical indentations along at least one of the surfaces
24 for receiving rolls of material. Further, such an elongated bar
of expanded foam material includes a plurality of recesses located

1 within or adjacent i:o the side portions of the
2 semi-cylindrical indentation to provide flexural cushioning.
3 These bars restrict movement among the rolls of the stack
while,
4 at the same time, a~:e of sufficient strength to prevent
crushing
and collapse of the stack. Also disclosed is one embodiment
which
6 provides an integral lip along the outside edge of a
7 semi-cylindrical in~3entation of a supporting bar to protect
an
8 otherwise exposed egad of a material roll from damage.
9
In use, the elongated bars may be placed between the
11 bottom layer of rolls and the supporting pallet, between
each
12 layer of rolls in t:he stack, and on top of the stack.
In one form
13 of stacking arrange;nent, each layer contains a number
of rolls of
14 material arranged in parallel and axial orientation. The
supporting bars may be arranged parallel to one another
and spaced
16 apart with the end portions of each roll supported in
a
17 semicircular indentation provided by adjacent spaced bars.
18
19 The bars located in the interior of a stack as
disclosed, receive and support the ends of axially adjacent
rolls.

22 interiorly located bar may be required to support the
end portions

the stack
24 has been minimized by securing a palletized stack with
strapping
and stretch wrap film.

2 The elimination of strapping from a pallet containing
3 a multi-layer stack under certain loading configurations has been
4 found to cause alignment problems within the stack because of
vibrations of the type experienced during shipping and handling.
6 Slight movements between the components of the stack may be caused
7 by tilting, jarring, or similar forces encountered in shipping,
8 which might result in either a roll or a supporting bar shifting
9 within the stack. If such movement becomes large enough, the
relative axial displacement of a roll may cause it to drop off a
11 supporting bar. Alternatively, such movement may cause the rolls
12 to be pushed together which might cause damage to the roll ends.
13 The invention set forth herein provides a solution to these
14 problems.

1 DETAINED DESCRIPTION OP' THE INVENTION
2
3 A first preferred embodiment 100 of the malleable
4 ragglestick as shown in Fig. 1 is intended to support and confine
an upper row of circular pipe product from the bottom and support
6 and confine a lower ~:ow of product from the top and comprises a
7 plastic tube 110 of I?'ig. 2 having a circular axial cross-section
8 as shown in Fig. 3 amd having two (2) sets of a multiplicity of
9 depressions, namely ~3 set of top depressions 130 and a set of
bottom depressions 1;50 as shown in Fig. 4 , generally spaced
11 apart.
12
13 Other possible cross-sections are shown in Fig. 11 and
14 Fig. 12.
16 Each top depression 130 has first midpoint 132 and
17 each bottom depression 150 has second midpoint 152.
18
19 The set of top depressions 130 of said first preferred
embodiment 100 are fabricated so that the entire surface of each
21 top depression 130 will fit snugly against the outside wall of the
22 upper product which is supported by top depressions 130 and thus
23 each top depression 130 has a first radius 133 nearly equal to the
24
26
19
SUBSTITUTE SHEET (RULE 26)
CA 02219363 1997-10-24
WO 96/34221 PC"T/US96/06009
1 outside radius of the upper product. Each first
2 midpoint 132 is spaced apart from each adjacent first midpoint 132
3 by a distance equal to twice (2x) the first radius 133.
4
The set of bottom depressions 150 of said first
6 preferred embodiment 100 are fabricated so that the entire surface
7 of each bottom depression 150 will fit snugly against the outside
8 wall of the lower product which supports each bottom depression
9 150 and thus each bottom depression 150 has a second radius 153
nearly equal to the outside radius of the lower product. Each
11 second midpoint 152 is spaced apart from each adjacent second
12 midpoint 152 by a distance equal to twice (2x) the second radius
13 153.
14
The first radius 133 may be equal to the second radius
16 153.
17
18 The diameter of the tube 110 is chosen so that the
19 area of each top depression 130 and each bottom depression 150 is
sufficiently large to provide the necessary support. The length
21 of the tube 110 is equal to the width of the bed of the truck
22 trailer or railroad car or other such determining dimension. The
23 thickness of the wall of the tube 110 is large enough to maintain
24 structural integrity and small enough to facilitate the
fabrication process.

the
fabrication device 200 at the rack entrance 201 and exiting
the
16 heating unit 202 at t:he rack exit 203. The heated unshaped
tube
17 110 is repositioned by the mechanism to control material
advance
